MP 1,1-5,1 Video Card Recommendation for Mac Pro 5,1 in 2024

Just one last question, should I remove the 580 and put the 680 back and than install Mojave and install the the 580 back?

Mojave does not install from createinstallmedia USB installer if you have a NVIDIA 6xx/7xx GPU, you have to install it from High Sierra to another drive.

Since right now your RX 580 does not have pre-boot configuration support - this can be solved with BootROM reconstruction service later - and will make your life miserable trying to do a clean install, do it with two steps. Install High Sierra with your AppleOEM GPU or the GTX 680 if is a flashed one and then install Mojave to a second drive.

You can even install the RX 580 to High Sierra, it will work more or less poorly, but will work. Apple only really cooked the RX 580 drivers with Mojave release.

Hi again, did what you said I’m pretty sure. Installed an old 3tb on my cd drive, made two partitions, installed high sierra in one partition and Mojave on the second partition. The Radeon 580 works fine. As soon as I installed back my SSD’s and Nvme with Monterey and Ventura I can not boot. I can not even boot from the Ventura installer usb. I know I’m doing something wrong, I’m missing or overseeing something. Maybe I have to do the bootrom reconstruction as you mentioned. If this is what I need can you please show the link? Thanks again

Nice, good news!

You are not doing it wrong, you're just forgetting that don't have access to Apple native BootPicker right now and like I've said to you before, OCLP does not allow you to change the GPU that you used for the installation for one that use different drivers - since OCLP removes the drivers for any other GPUs.

I’m missing or overseeing something.

Yes, you installed a PC GPU, so, nothing works display wise until the macOS GPU drivers are loaded on the last half the boot process.

Also, no way to access/use the Apple native BootPicker right now.

Maybe I have to do the bootrom reconstruction as you mentioned. If this is what I need can you please show the link? Thanks again

You gonna need to reinstall the unsupported macOS releases with your RX 580 and for that you gonna need pre-boot configuration support. OCLP without pre-boot configuration support makes it extremely difficult to install.

To have pre-boot configuration support with a RX 580, you gonna need EnableGop, the easiest way to obtain it is with the BootROM reconstruction service, you'll get your BootROM repaired for the early-2009 cross-flashing issues, fully upgraded to mid-2012 standard and will have pre-boot configuration support with PC GPUs.

I've sent you a PM.
